提高查干凹陷火山岩岩性识别准确率

Improving Lithology Identifying Accuracy of Volcanic in Chagan Sag

查干凹陷火山岩岩性识别准确率偏低,严重影响了录井质量,也不利于火山岩储层及油气层的评价。为提高火山岩岩性识别的准确率,从分析岩性识别影响因素入手并针对性的制定具体措施,主要包括:火山岩知识培训、微观特征学习及引进录井新技术设备,且进行了有效的实施,提高了查干凹陷火山岩岩性识别准确率,为火山岩油气藏的勘探开发提供了一定的技术支持。

The low lithology identifying accuracy of volcanic in Chagan Sag seriously influences logging quality, and it is also not fa- vorable to the evaluation of volcanic reservoirs and oil/gas reservoirs. In order to improve the lithology identifying accuracy of vol- canic, some measures are taken based on the factors of influencing the lithology identifying accuracy of volcanic, including knowledge training on volcanic, learning the microscopic characteristics of volcanic and introducing new logging technique and equipment. The implementation of the measures improves the lithology identifying accuracy of volcanic in Chagan Sag, which provides the technical support for the exploration and development of the volcanic reservoirs.
